I bought a piece of 1.5 inch stiff foam to try to fix a sag in a bed. It didn’t work but having that thick piece of solid foam around has been a life saver.
Need something flat to put a laptop on? Throw it on the foam. Going to be doing something that requires you to be on your knees for a while? Get the foam!
It went from stupid purchase to something I’d gladly replace if it broke.
Alternatively, get a mirror that hangs on the back of the door and shave in front of that (if using a buzzer that you don’t need to keep rinsing in the sink). It’s so much easier to just grab the broom or vacuum cleaner and get it all off the floor in two seconds than chasing stray bits of hair around your faucet handles and random objects on your counter.
Also, if you do have to clean up those bits of hair on your counter, use a piece of TP. Wet it a little so that hair sticks to it better, then either fold each wipe into the middle or start a new piece before doing the next wipe so it doesn’t just leave old hairs behind when you’re trying to pick up more of them.
